how to use strategy groups?

Can someone please tell me, how do you use strategy groups? I'd like to analyze a group of strategies I've made.
Thanks!

Successful traders establish rules that guide them in their forex operations, on the one hand, to avoid making common mistakes, such as guided by subjective elements, and also because the development of a strategy involves the study of market behavior, and repeat this study For each order would be an impossible effort to perform. Forex strategies are systems that establish trading rules. Strategies serve as guides in the placement of orders, both inbound and outbound, as well as stop loss.

One na tip of the most important parts of Forex is the trading strategy. Look for online trading strategies or develop one with your own hands. What really matters is that you try them on a demo account to find out if they are profitable....

So you have created some strategies and combine them in a group, but you don’t know how to use them? That sounds a bit contrary..
